where \(d_i\)  is \(i\) 's degree. Notice that \(r_i\)  goes from 0 to \(d_i - 1\) .It is also well related to the notion of local clustering, which can be thought of as a normalized version of redundancy ranging from 0 to 1. It can easily be shown that the relationship between the local clustering \(q_i\)  and redundancy \(r_i\)  of a node \(i\)  of degree \(d_i\)  is given by: \(q_i = \frac{r_i}{d_i - 1}\)  [1]}.
Then, the effective size \(s_i\)  of node \(i\)  is defined as:
\(s_i = d_i - r_i.\)
